<h3>DEM Generation Operator</h3>This operator converts interferometric phase to digital elevation map. <h4>Input and
    Output</h4>
<ul>
    <li>The
        input to this operator the output of Stitch operator.
    </li>
    <li>The output of this operator is the elevation band.</li>
</ul>
<ol>
</ol>
<h4>Parameters Used</h4>&nbsp;&nbsp; The following processing parameters are needed for this operator (see Figure
1):<br>
<ul>
    <li>Digital Elevation Model: The digital elevation model used in reference height calculation.</li>
    <li>DEM Resampling Method: The resampling method used in getting elevation from DEM.<br>
    </li>
</ul>
